AUTOMOBILE SEAT-COVER FASTENEB.

.Application led April 13, 1927. Serial No. 183,577.

This invention relates to al fastener and more particularly to a construction of fastener to attach seat covers tov automobile seats, and has for its primary object the construction of a device that not only facilitates the proper attachment of the covers to the seat but will be secured to the seat proper to be readily detached.

An object of the invention is the construction of a fastener of a' design to penetrate the upholstery of the seat and to assume a nal position paralleling the inner surface of the upholstery of the seat so that the fastener will so interlock with the upholstery that the usual strain connected with` the stretching of the seat covers will increase tle effective engagement between the fastener and the seat. l i Another object of the invention is the; design of a fastener that may be cheaply manufactured and which can' be effectively interlocked with the seat upholstery and which includesin its construction snap elements, thereby enabling the covers to be readily removed when found necessary.

A feature-of the invention is the construC-.

tion of a fastener of two elements having a snap connection, one permanently carried by the seat cover, the other detachably secured tothe upholster of theseat.

` Besides' the a ove, my invention is dis-A tinguished in the construction of afastener that interlocks with the upholstery of theseat"ina direction at right angles to the direction of strain of the seat cover when stretched tautover the surface of the seat.

' With these-and other objects in view, my .invention will be better understood from a description of the same when taken invv con- 40 nection with the accompanying' drawing, whereinz- Figure 1 is apsectional view of .a ortion of a seat and a cover therefor showing the application'of myfimproved fastener; Y 46,' v igure 2 is a perspective view of one' section of the button; v

companion members 4or sections 2 and 3, the 70 former constructedas a socket member permanently secured to the cover B and the latter in the form of a ball member detachably interlocking with the upholstery C of the seat D. The fastening element `or member 3 forming an important part of my inventionv i's constructed to provide a spear-shaped shank or pin 4 having a restricted neck portion- 5 a continuation of the shank 4, and providing a. pair of shoulders 6 for abutting engagement with the upholstery afterl the shank has penetrated the same.

Associated with the necle is a head 7 pro-y vided with a ball 8. for snap engagement with the button or socket, sectlon 2. -Referring to Figure 3, it will be noted that in the final construction of the fastener, the head parallels the shank due to the loop formation of the neck and thus the shank is enabled to be positioned in parallelism with the under surface of the upholstery, as shown in Figure 1, to have an interlocking engagement therewith with the head positioned for yieldable movement toward and away from the shank so as to facilitate the vinsertion `ofthe fastener into the upholstery ciated that after the cover `2B has been 100 Figure 3 is a perspective View illiisttating""lV stretched around the 'surface of the seat, the

In Figures 4 to 7 inclusive, I have ills- .trated the head 9 formed integral with the shank 10 with the ball 11 struck. from the head laterally thereof. 4The shank 10 mayor may not be provided with a reinforcing rib 12 and shoulders 13 for interlocking engagement with the upholstery.

Figures 8 and 9 illustrate in a; diagrammatic manner one method of manufacturing the fastener which consists -in placing a sheet of 'metal 14 under a suitable stamping machine and stamping therefrom the blank 15 having the head 16 and neck 17 and shank 18. In. the final stamping operation, the

head may be formed with a depression 19 to 'can be effectively secured to the button element carried .by the covering so as to assure a neat fitting of the covering over the surface of the seat irrespective of theA particular formation of the seat. It will also be appreciated that the design and construction p of the various parts is such that the covers may be readily stretched and when stretched the members may be readily snapped into engagement with each other and the stretching action of the covers relied on to increase the effective binding engagement between the fastener and the upholstery. Although there is provided a rigid connection between the various element due to the direction of pull of the cover, the latter may be very readily removed by exertinga separating pull on the element in a direction at right angles to the cover and thus the cover may y matassa be readily 'removed when desired, and if desirable the fasteners may be readily disconnected from the seat.

It is, of course, to be understood that the fasteners may be constructed in various other shapes than lllustrated and various other attaching features may be incorporated with the fastener and, therefore, I do not desire to be nlimited in any respect whatsoever ex cept asset forth in the following claims.

1. A one-piece fastener stamped to provide a spear-shaped shank, a necka continuation of the shank, and a head a continuashank, and a ball formed integral with the head.

3. 'A fastener formed from a single piece of material to provide a shank, a head yieldabl connected to and paralleling the shank an a ball struck laterally and centrally of the head.

4. A fastener comprising a snap element and a penetrating prong curving from the edge vof said element to extend in parallel spaced relation with approximately the entire under surface of said element.

5. A fastener comprising a snap element of disc formation and a penetrating prong curving away from the peripheral edge ,of said element to extend in spaced parallel relation with the entire under surface of said element andv further to extend a predetermined distance beyond the element.

In testimony whereof I aiix my signature.
